Abstract :
The design of a low-distortion, wide-band amplifier with 75-/spl Omega/ input and output impedances is described. Simultaneous shunt and series feedback is used and design equations are derived for terminal impedances, forward gain, loop gain, and noise figure. The advantages of a Darlington connection for low distortion are described. For 0-dBm signal levels, the amplifier achieves third-order intermodulation products of -88 dB relative to the carrier at 300 MHz and 12 channel cross-modulation (CM) of -77 dB at channel 13.
